docker拉取镜像报错Error response from daemon: Get "https://registry-1.docker.io/v2/": context deadline exceeded

Docker pull拉取镜像报错“Error response from daemon: Get "https://registry-1.docker.io/v2”解决办法(已经排除网络原因，仍无法拉取)

一、报错信息

[root@localhost ~]# docker pull nginx

Using default tag: latest

Error response from daemon: Get "https://registry-1.docker.io/v2/": context deadline exceeded

二、检查daemon.json 文件

[root@localhost ~]# cat /etc/docker/daemon.json

{"registry-mirrors": ["https://registry.docker-cn.com","http://hub-mirror.c.163.com"]}

如果没有文件创建编辑（可额外添加阿里云的镜像加速阿里云镜像加速器）

1.编辑daemon.json

{"registry-mirrors": ["https://registry.docker-cn.com","http://hub-mirror.c.163.com"]}

2.重启服务

[root@localhost ~]# systemctl daemon-reload

[root@localhost ~]# systemctl restart docker

三、查看dns解析

[root@localhost ~]# dig @114.114.114.114 registry-1.docker.io

;; ANSWER SECTION:

registry-1.docker.io. 74 IN A 3.216.34.172

registry-1.docker.io. 74 IN A 34.205.13.154

registry-1.docker.io. 74 IN A 44.205.64.79

四、添加host解析

[root@localhost ~]# cat /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

3.216.34.172 registry-1.docker.io

五、重新拉取镜像

[root@localhost ~]# docker pull nginx

Using default tag: latest

latest: Pulling from library/nginx
